5 Replacing an Optical ModuleAn optical module implements optical-electrical conversion, enabling optical transmissionbetween a BTS3902E and other devices. You must disconnect the fiber optic cable from anoptical module before replacing the optical module. Disconnecting the fiber optic cableinterrupts the transmission of optical signals.PrerequisiteslThe type and number of optical modules to be replaced are confirmed, and new opticalmodules are ready.lTools and materials, such as electrostatic discharge (ESD) gloves, M4 Phillipsscrewdrivers, and an ESD box or bag, are ready.ContextlThe optical module is installed on the OPT0 or OPT1 port on the BTS3902E.lOptical modules are hot-swappable.lIt takes about five minutes to replace an optical module on the BTS3902E, which involvesdisconnecting the fiber optic cable, removing the faulty optical module, inserting a newoptical module, reconnecting the fiber optic cable, and waiting for the link on the Ethernetoptical port to resume.ProcedureStep 1 Wear ESD gloves.NOTICETake proper ESD protection measures; for example, wear ESD gloves, to prevent electrostaticdamage to the boards, modules, or electronic components.Step 2 Record the connections of the optical module and fiber optic cable.Step 3 Press the latch on the connector of the fiber optic cable, and then remove the connector from thefaulty optical module.BTS3902E WCDMASite Maintenance Guide 5 Replacing an Optical ModuleIssue 06 (2014-05-16) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.18
CAUTIONDo not look into the fiber optic cable or optical module without eye protection after the fiberoptic cable is removed from the optical module.Step 4 Lower the puller on the faulty optical module, and then pull the puller until the optical moduleis removed from the BTS3902E.Step 5 Prepare an optical module of the same type as the faulty optical module according to the labelon the module. Install the new optical module onto the BTS3902E.NOTEThe optical modules to be installed must match the rate at the fast Ethernet or gigabit Ethernet (FE/GE)port.Step 6 Insert the fiber optic cable connector into the new optical module.Step 7 Check the transmission of FE/GE signals by observing the status of the indicators labeled O/Eor O. For details about the status of the indicators, see BTS3902E Indicators in BTS3902EWCDMA Hardware Description.Step 8 Take off the ESD gloves, and pack up all the tools.----EndFollow-up ProcedurelPlace the removed optical module into the ESD box or bag. Then, place the ESD box orbag into a foam-padded carton or the packing box of the new module.lFill in the fault form with detailed information about the removed component.lContact the local Huawei office to handle the faulty optical module.BTS3902E WCDMASite Maintenance Guide 5 Replacing an Optical ModuleIssue 06 (2014-05-16) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.19
